The present invention-relates to'gasproducers, andhas particular reference to the dispositiongandsupport, in a rotary gas producer, ofthe main fuel-containing section orshell.

The lnvention involves certain structural 1 improvements in the type of rotary gas producer shown and described in United States- Letters Patent to 'Jefferies, 'No'. 1,2t" ,0.15,

10' ing the ffuelshell directly upon the ash pan dated January 29,'1918,by way of support of the rotary porducer in theabsence of obstruction either tothe free descent of ashes:

from said'shell into said pan; or to the free sweepof an ash removing plow over the 'surface of said'pan. Other and further objects and. advantages of my invention are set forth i @hereinafter'in the following detaileddesclli pi i r tionthereof;'in connection with said descr1p-- "tiongreference is made'to the accompanying drawings, in which-#- Fig; 1 is-a verticalsectional view of the lower portion of a gas producer embodying thereof being shown in asection taken in the my invention. t f

The numeral l indicates theloweriportion' V ofa gas producing chamber, inclosed within "-ialwall or shell'2 which constitutes the "fuel tained at a level high enough to make a seal Q with the depending; skirt 6 of shell 2, thereby I "to prevent the escape of gases through the an- 7 nular space left between walls 5 and skirt 6 for the withdrawal of ashes. i i

As in the aforesaid J efieries patent, the hl "pan 3 is rotatably supported and" driven, the

support being afforded by a plurality of-rollers 7 (onlyon'e beingshown) arranged in a circular series beneath a ring 8 on the bottom" o fls'aid pan, and the drive being'secured by a bevel pinion 9 inmesh with a bevel gear 10 on said ring 8. As set forth in the aforefor such rotation, said'shellshould have its I supportdirectly upon said ash pan, through connections which preserve anunobstructed space wlthin said pan for the operation ,ofian 'a'shremoving plow, indicated by the numer- V al11.- I

These connections, in' the aforesaid Jefferies patent, take the form of a plurality "of hollow blast arms radiating from the center oftheash pan, and supporting on their I outer endsian annular mantle onwhich the brickwork of the shell is'erected; saidhollow blast arms of Jeflferies', lying wholly. abovethe level reached by the sealing waterfcontained in'the ashpan, are frequently bur'nedfout by the intenseiheat'of the surrounding incan descent fuel, and moreover, said hollow arms f are of such thicknesslaterally that they offer undue resistance to the free descent into the ash pan of'that'portion of the'. mass of fuel 7 ing water seal skirt of theifuel shell; the

tenden'cyyin zthe operation 'of the 'Jefferies deyic'e, is for arches of elinkers'to form across the segmental spaces of limited area lefthe- *tweent'he hollow blast arms, and these arches,

. v V v t and ash whichiis s'urround'edby the dependv Like reference characters refer tolike parts which seriously impede the descent ofashes intothe pan, must frequently'be broken by hand-poking "of the fire;

According to my invention, the above; mentioned diificultiesare overcome bythe novel construction (of the supporting connections i between the ash pan 3 and the fuel section or i shell2; As shown inFig. 1,'a tube or sleeve a Il2 is secured by means "of 'itsbannular base" Y flange. rate measure of ashfpan bottom a, with thelpassage through said-tubeforming 3, :COHiZlfliIafiOII OfbhG centralgblast 'passage 1 4; x x

The tube or sleeve 12, as best shownin Fig. 2, is formed exteriorly *with; three pairs of j longitudinally disposed ea-rs or lugs 16, 16, these pairs of ears being spaced equidistantly on the circumferenceof said sleeve, and each to be carried out under-the most favorable conditions, and'at the same time the support ing armslz', 17,-whiclrconnect the fuel shell iair rovidin at' tliegto and bottom re andthe ash anjfor rotation"in'iunison are p b i D 7 isterin bolt 'ap'erturesfor the attachment of the arms 17, (three in number), that furnish so 'constructed'ja'nd arranged? as to leave the maximum space in the area lnclosed'by skirt support, as hereinafter described, for "the ff the r c f ashes into -P shell 2.

Each arm 17 takes the formof a thin vermi-nishes in height, by convergence of-its upper and lower edges, from the maximum height at 'its inner'end, corresponding sub- 1 stantially-to the heightlof the sleeve=1-2. At said inner end, each armfl7 ;fits snugly-be tween a pair of ears 16, 16, and is held in place, at the top and bottom respectively,-by 1 suitable bolts 18 and 19, passing throughthei ear apertures and through gcorresp'onding apertures of said arm. f Justc abeve its upper I boltlS, each; arm 17 provides ail-upstanding V 1 lug 20,the ,three' lugs serving-tosupport P01 1; saldfishen ifrom "Sa 1; pa {111' h .a-ndcenter the blast cap 15 byftheir 'receptionl in an annular recess'21-on:the'under side of;
